Deacetylanisomycin is a derivative of the protein and DNA synthesis inhibitor anisomycin with antimalarial and anticancer activity. It inhibits the growth of the P. falciparum strains K1 and T9-96 in vitro (IC50s = 40.29 and 33.57 μM, respectively). Deacetylanisomycin is cytotoxic to LU99 lung carcinoma and MCF-7 breast cancer cells (IC50s = 23 and 34 μM, respectively). It has been used as a negative control for assessment of protein synthesis inhibitor activity in molluscan neurons.
